LOUIS, MISSOURI, A CORPORATION OF MISSOURIREFRIGERATOR-C011 MOUNTING- This invention relates to refrigeration coilmountings for installing the expansion or evaporator coils of arefrigerating apparatus in the ice compartments of refrigerators.

It is an object of this invention to provide means for mountingrefrigeration coils in ice compartments of varying sizes without havinbolts projecting through the wallsthereo and with the minimum of fittingor special equipment for iceboxes of varying sizes and makes. Heretoforewhen installing a refrigerating apparatus in connection with existingrefrigerators it has been necessary to provide a number of stock size ofexpansion or evaporator coil assemblies for each capacity to fitdifferent sizes of ice compartments of the same capacity and then toindividually fit the proper coil in the compartment. It is, therefore,an object of this invention to reduce the number of sizes required tothe number of capacities desired and to provide an easily adjustablemountingmeans for these varioussizes capable of mounting a unit of agiven capacity in various shapes of refrigerator ice compartments.

Other and further important objects of this invention will beapparentfrom the dis closures in the drawings and specification.

This invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

On the drawings:

Figure 9 is a section on the line IXIX of Figure 8.

- Figure 10 is an enlarged fragmentary detail section of the mounting ofFigures 9 and 10.

As shown on the drawings:

Theusual refrigerator or ice box 10 is provided with an ice" compartment11 closed by a door 12, the compartment having a metal lining 13 insidethe insulation and box wall construction 14. The expansion tank 15,coils 16 and drawers 17 comprise the refrigeration unit which is to bemounted in the ice compartment'and connected to the refrigeratingapparatus drawings.

The structures shown in Figures 1 to 7 contemplate supporting therefrigeration unit from a pair of parallel adjustable bars comprisingsleeves 18 having either a pin cap 19 proper, which is not shown in theto be forced into the lining 13 as shown in 7 Figures 4 and 5: a milledor roughened cap 20 as shown in Figure 7 or a cup-like rubber cap 21 asshown in Figure 6, the last two frictionally engaging the lining. Eachbar comprises 'a pair of the sleeves 18 spread by means of a longthreaded rod 22 with nuts 23 engaging the ends of the sleeves, thethreaded rod and nuts acting as a jack to force the caps into holdingcontact with opposite walls of the ice compartment. The tank 15 issuspended from these bars by means of U bolts 24 passing around the tankand secured to bars 25 which are hung from the bars 18 by the hook bolts26.

In the use of this form of mounting it will i of the same constructionas the bars 25, by means of the U bolts 24 as before, and which may havea number of bolt apertures 28 in eac end with notches 29 in the barbetween the apertures so that if'the bar is too long for the width ofthe refrigerator compartment a section or two can be broken off the endof the bar to reduce the length thereof. Two of these bars 27 areordinarily used and are supported against the top of the ice compartmenton bars 30 which in turn'are supported by lag screws 31. The lag screws31 are ordinarily mounted in the top of the refrigerator box when thesame is built, it being desirable that no bolts project through the tosurface of the outer cabinet because such bo ts would be so cold theexposed surfaces would condense and freeze moisture from the air at roomtemperature, thus producing objectionable frosted areas on the surfaceof the cabinet.

An important feature of this invention resides in the adjustability forheight of the expansion tank 15 through the threaded stems of the Ubolts 24 and the tank clampingbars 24" associated therewith. Nuts 24 onthe ends of these stems preferably rest in recesses in the bars 27 thusmaking it possible to have said bars flush against the top of therefrigerator compartment. To take care of difiercnt required heights inthe field it is onl neccssary for the person making the instal ation toproperly iposition sto nuts 24 on these stems, cut 0 the ends 0 thestems if necessary and then screw the nuts 24 in position on the uppersides of the bars 27. It will thus be evident that I have provided aconstruction which meets the contingencies of a variety of installationswithout the necessity of special tools or fittings.

I am aware that many changes may be made and numerous details ofconstruction may be varied through a wide ran c without departin fromthe principles 0 this invention and therefore, do not purpose limitingthe patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In combination with the ice com artment of a refrigerator, extensiblebars a apt- ,ed to securely engage the walls of said we compartment andmeans adapted to suspend ars,

' a refrigerating unit from said extensible said means being underslungrelative to said bars and bei readily removable from said compartment ymerel rs. 2. In combination with the ice compart-.

ment of a refrigerator, extensible means adapted to be forced intoengagement with the walls of said ice compartment, a refrigerating unit,and means for suspending and supporting said unit from said extensiblemeans.

8. Supporting means for mounting a rey raising same 05 saidfrigeratorunit in various sizes of ice compartments comprising a pair ofextensible ars including aligned members having means on the endsthereof adapted to engage opposite walls of the ice compartment, meansadapted to force saidaligned members apart to engage the opposite wallsof the ice compartment and mounting means for said unit connected tosaid bars in such a manner as to cause said refrigerator unit to handfrom said bars. v

. 4. Mounting means for refrigerating units comprising a plurality ofsupporting bars, transverse supporting bars ad]ustably supported therebyand U shaped supportin means adjustably secured to and supported by saidtransverse bars.

5. Mounting means for refrigerating units comprising a pair ofsupporting bars, transverse bars supported thereby and adjustablethereon and U bolt clamping and supporting means adjustably mounted onsaid transverse bars.

6. A mounting device for a refrigerator unit including a cylindricaltank, said mounting device comprising a support and means connected tosaid support and shaped to receive the tank for directly supporting andpositioning the unit, said means being adjustable to accommodate tanksof various diameters.

7 A mounting device for a refrigerator unit comprising a supportingstructure formed to be adjustably fitted within and supported fromtheside walls of any one of a number of different sizes of chambers of arefri erator in which the refrigerator unit is to positioned andsupporting means adjustable to receive various size units and formed soas to be suspended from said structure after said structure has beensecured in place within the chamber.

8. A mountin device for accommodating different sizes 0 refrigeratorunits comprisng a supporting frame, means for suspendmg the refrigeratorunit from the frame and readily detachable from said frame by liftingsame from the frame, and clamping means for securing the unit to saidsuspending means independently of said frame.

In testimony whereof I have hereunto subscribed my name.
